Readings and some tasks for the 3rd class

I am sending links to the video we used in the previous lesson

I would like to invite you to think about the ways how to work around the censorship (in China, Saudi Arabia and others) based on understanding you already have. Some terms might help, if you don't understand them, their definitions can be found elsewhere:
- packets
- routers
- firewalls
- Internet as the network of networks

So, how China actually does the filtering?

In the upcoming class, we still stay on the technical side, talking about
- IP addresses
- DNS, domains and registration

Please find and study the wikipeadi entries for those things:
IP address
ipv4, ipv6 (don't go into details if it does not interest you, but please scan it at least)

Read this fairly informative tutorial on DNS:

I would also like to ask you to reread the article by Vannevar Bush (you'll find the link in the 1st lesson's page) and try to find out the predictions that happened, what became reality (now).

Please, think until the next meeting whether you want to know more details about HTML language (this class will never be so extensive to teach somebody to write HTML pages, but we can stay with that topic longer, covering details and differences of (x)HTML and XML, SGML - all of them are often [and perhaps too much] mentioned by various people, some of whom cannot tell the tag from page heading elements) We can skip the topic mentioning only the most important parts, or we may dedicate one lesson or two to it.
